Design goal: Allow the use of layout "modules", which are to LaTeX packages as layout files are to LaTeX document classes. Thus, one could have a module that defined certain character styles, environments, commands, or what have you, and include it in various documents, each of which uses a different document class, without having to modify the layout files themselves. For example, a theorems.module could be used with article.layout to provide support for theorem-type environments, without having to modify article.layout itself, and the same module could be used with book.layout, etc.
This third patch just re-factors some code presently in QCitation*. (It also incorporates some bug fixes that have been committed separately.) We're going to use essentially the same set of widgets for choosing modules that is used for choosing citation keys, so we pull the controlling logic out into a new class, QSelectionManager. I did not make this a QWidget. That seemed to me to be overkill, and it would have made things much more complicated, I think...and I'm not all that experienced with Qt, anyway. Anyone who wants to do that is of course welcome.

The changes are essentially of three types.
First, the std::maps previously used here for storing BibTeX data have become full-fledged classes and so what were previously just a bunch of functions have now become methods of these new classes. This leads to a lot of minor changes in other files, to adapt to the new signature. The changes in insets/ are mostly of this kind.
Second, there are some slightly more substantial changes in src/insets/InsetBibtex.cpp. We now store lists of the field names and entry types that have been used.
Finally, there are the changes to the citation UI. These are mostly straightforward, though adding the new functionality exposed some inadequacies in the previous code that also had to be fixed.
One other change: BibTeX keys are now docstring. This solves some Unicode issues.
